Well my NOTE has the Exynos chip which uses smaller scale parts (nm) and because of that it is more efficient.

It has a 1.4GHz processor so this efficiency brings it close to 1GHz drain.

However it uses 2 cores, but since it can handle the load properly the strain on the battery is equivalent to a single core.

So there you have it, the NOTE uses 1GHz Cortex A8 power but delivers 1.4GHz Dualcore Cortex A9 performance. And since its (x1.7) battery is much larger (2,500mAh), its able to also last longer, herp derp troll thread
